a random sample of 81 executives (these 81 include both male and female) is drawn for the purpose of estimating the population proportion of females and the mean age of all female executives. The sample contains 33 female executives and for those ladies, the sample mean and standard deviation are 46.5 years and 6.8 years, respectively. We now want to build a confidence interval for the mean age of all female executives. a.: check that the conditions to build a...
